Abstract
PURPOSE: Management of chylous ascites is poorly understood with no management guidelines. We retrospectively reviewed patients treated for chylous ascites at our institution to evaluate efficacy and safety of lipiodol lymphangiography and embolization. MATERIALS AND METHODS: Seven patients underwent percutaneous interventional management of chylous ascites (average age 52.5 years, 3 female, 6 post-surgical, 1 pancreatitis) from 2012. All patients underwent lipiodol inguinal lymph node injection. Adjunctive glue embolization was performed if a leak was identified. Data were collected on the cause of chylous ascites, conservative management strategies, procedural details, and success. RESULTS: All patients had chylous ascites refractory to conservative management. Preprocedure lymphoscintigraphy identified a retroperitoneal leak in 6 patients. Seven patients underwent 12 lymphangiogram procedures; 8 were performed at our institution. Lymphangiography identified a leak in 5 patients (71%). Success was achieved in 2 patients (28%) treated at our institution after glue embolization following cannulation of the leaking lymphatic channels and 1 patient (14%) after lymphangiography alone for an overall success rate of 43% (3/7). Two patients (29%) were successfully treated after one procedure. Two patients (29%) unsuccessfully treated at our institution were referred to a specialized center in the United States. No 30 day post procedural complications. CONCLUSIONS: In our experience, lymphangiography and embolization was a safe, relatively effective and minimally invasive method for treating medically refractory chylous ascites. Complex cases required referral to a specialized institution with resources unavailable at our tertiary care center.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
